Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a kettle. Background Art

[0002] In daily life, people are used to drinking boiled water, so electric kettles are almost essential tools for life. Regarding drinking water, we often face a problem. After the water is boiled, its temperature needs to be lowered before drinking. However, the efficiency of heat exchange between the kettle and the air by simple heat dissipation is very low, that is, it takes a long time for the water temperature to drop to a suitable drinking temperature. This greatly affects our daily life and wastes time. Most electric kettles are equipped with heat insulation covers on the surface, which only consider heat preservation but do not have cooling function. Compared with heat preservation, rapid cooling function is also necessary. For example, warm water is needed to feed medicine to children and to brew beverages such as protein powder.

[0003] At present, some electric kettles have a coolant flow channel between the inner tank and the outer shell, and use the coolant to cool the liquid in the inner tank, so that the electric kettle has a cooling function. However, the heat absorbed by the coolant will also be transferred to the outer shell, causing the outer shell temperature to be high, which may scald the user. Utility Model Content

[0004] Based on this, it is necessary to solve the above problems of the existing kettle and provide a kettle.

[0005] The hot water kettle provided in the present application comprises a hot water kettle body, a fan device, an air duct housing and a stirring device, wherein:

[0006] The kettle body is provided with a water storage cavity and an installation cavity, a spout connected to the water storage cavity, and a first through hole connected to the installation cavity. The installation cavity is provided with the fan device, and the air inlet of the fan device is connected to the first through hole.

[0007] An air duct housing, the air duct housing is connected to the kettle body, the air duct housing is provided with an air guide channel, the outlet of the air guide channel is communicated with the water storage cavity, and the inlet of the air guide channel is communicated with the air outlet of the fan device;

[0008] The stirring device comprises a driving motor and a stirring blade, wherein the driving motor is located in the installation cavity, the stirring blade is located in the water storage cavity, and the stirring blade is drivingly connected to the rotating shaft of the driving motor.

[0009] The hot water kettle disclosed in the present application includes a hot water kettle body, a fan device, an air duct housing and a stirring device. The air outlet of the fan device is connected with the inlet of the air guide channel. The fan device introduces external air into the fan device through a first through hole and accelerates the airflow through high-speed rotating blades, and then introduces it into the air guide channel. The airflow is input into the water storage chamber through the air guide channel, and heat is transferred between the airflow at a lower temperature and the water at a higher temperature, thereby accelerating the cooling. A stirring blade is arranged in the water storage chamber, and a driving motor drives the stirring blade to rotate in the water storage chamber, so that a vortex is formed in the water storage chamber, thereby increasing the heat dissipation area, accelerating the heat transfer between the airflow and the water, and further improving the cooling effect. In addition, the stirring blade rotates slowly when the water is about to boil, which can eliminate the formation of bubbles and achieve a silent effect.

[0010] In one embodiment, the stirring blade is a rod structure, the length direction of the stirring blade is parallel to the horizontal direction, and the length of the stirring blade is smaller than the radius of the water storage cavity.

[0011] The kettle in the above embodiment further defines the structure of the stirring blade. By making the length of the stirring blade smaller than the radius of the water storage chamber, the stirring blade can generate a vortex with better effect when rotating in the water storage chamber, thereby avoiding the situation where the stirring blade is too long, resulting in a large stirring resistance and difficulty in generating a vortex, or the stirring blade is too short, resulting in a smaller vortex area.

[0012] In one embodiment, the center line of the stirring blade coincides with the center line of the water storage chamber.

[0013] The kettle in the above embodiment further defines that the center line of the stirring blade coincides with the center line of the water storage chamber, so that when the stirring blade rotates in the water storage chamber, a vortex with the center line of the water storage chamber as the axis is generated to increase the heat dissipation area and improve the heat dissipation efficiency.

[0014] In one of the embodiments, the outlet of the air guide channel is distributed on the top of the kettle body.

[0015] The kettle in the above embodiment further defines that the outlet of the air guide channel is located at the top of the kettle body, so that the airflow discharged from the air guide channel blows directly toward the water surface in the water storage chamber. In addition, by setting the outlet of the air guide channel at the top of the kettle body, the water storage capacity of the water storage chamber can be ensured, and at the same time, water is prevented from flowing back into the air guide channel when water boils in the water storage chamber.

[0016] In one of the embodiments, the outlet direction of the air guide channel intersects with the center line of the water storage chamber to form an angle a, and the angle a satisfies the relationship: 25°≤a≤30°.

[0017] The kettle in the above embodiment further defines that when the airflow is discharged from the air guide channel to the water storage chamber, an angle a is formed between the airflow direction and the center line of the water storage chamber, and the angle satisfies the relationship of 25°≤a≤30°, so that the airflow discharged from the air guide channel blows toward the middle of the water storage chamber, thereby maximizing the contact area between the airflow and the water surface and improving the heat dissipation efficiency.

[0018] In one of the embodiments, a one-way valve is installed in the air guiding channel, and the air guiding channel is selectively connected to the water storage chamber through the one-way valve.

[0019] The kettle in the above embodiment is further defined as a one-way valve provided in the air guiding channel, and the one-way valve can control the connection or cutoff of the air guiding channel with the water storage chamber.

[0020] In one embodiment, the one-way valve is a baffle, which can rotate relative to the air duct housing and form at least a first position and a second position. When the fan device stops working, the baffle is in the first position, and the air guide channel and the water storage chamber are disconnected; when the fan device is working, the baffle is in the second position, and the air guide channel and the water storage chamber are connected.

[0021] The kettle in the above embodiment further defines the one-way valve as a baffle structure, which can rotate relative to the air duct housing. For example, when the fan device is working, the airflow generated by it pushes the baffle to rotate from the first position to the second position. At this time, the one-way valve is in an open state, and the air guide channel is connected to the water storage chamber. When the fan device stops working, the baffle rotates from the second position to the first position under the action of its own gravity. At this time, the one-way valve is in a closed state, and the connection between the air guide channel and the water storage chamber is cut off.

[0022] In one of the embodiments, the air duct shell is distributed on the periphery of the kettle body, and two ends of the air duct shell are respectively connected to the kettle body, and a second through hole is formed between the air duct shell and the kettle body.

[0023] The kettle in the above embodiment further defines that the air duct shell is distributed on the periphery of the kettle body, and a second through hole is formed between the air duct shell and the kettle body. The air duct shell can be used as a handle, which neither affects the user's hand-held movement nor causes the overall volume of the kettle to increase, making the overall design of the kettle reasonable.

[0024] In one embodiment, the air duct housing is detachably connected to the kettle body. Since the air duct housing and the kettle body are detachable, the air guide channel can be cleaned separately to avoid the air duct housing being unable to be cleaned during long-term use.

[0025] In one embodiment, a first air filter is provided in the air guide channel. Based on the first air filter provided in the air guide channel, the airflow entering the water storage chamber is purified to avoid contamination of the water in the water storage chamber.

[0026] In one embodiment, the kettle body includes an upper cover, a kettle body, and a heating plate. The upper cover is arranged on the kettle body or the air duct housing. The heating plate is arranged on the kettle body, and the heating plate divides the space formed inside the kettle body into the water storage cavity and the installation cavity. The kettle body is provided with the first through hole, and the rotating shaft of the drive motor passes through the heating plate, extends into the water storage cavity, and is transmission-connected to the stirring blade.

[0027] The hot water kettle in the above embodiment further defines that the heating plate divides the space in the kettle body into a water storage chamber and an installation chamber. Specifically, the water storage chamber is above the heating plate, and the installation chamber is below the heating plate. The rotating shaft of the driving motor passes through the heating plate and extends into the water storage chamber to be transmission-connected with the stirring blade. A sealing ring is sleeved on the rotating shaft, and the sealing ring is used to seal the gap between the rotating shaft and the heating plate.

[0028] In one embodiment, the kettle body further includes a power socket, a hollow portion is provided on the power socket, the first through hole is connected to the outside through the hollow portion, and the power socket is electrically connected to the heating plate.

[0029] The kettle in the above embodiment is further defined as a hollow portion provided on the power socket, and the hollow portion allows the first through hole to communicate with the outside air. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0040] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0041] like Figures 1 to 4 As shown, this embodiment provides a kettle, comprising:

[0042] The kettle body 10 is provided with a water storage chamber 101 and a mounting chamber 102, a spout 121 communicating with the water storage chamber 101, and a first through hole 103 communicating with the mounting chamber 102. A fan device 20 is provided in the mounting chamber 102, and an air inlet of the fan device 20 is communicated with the first through hole 103;

[0043] The air duct housing 30 is connected to the kettle body 10, and the air duct housing 30 is provided with an air guide channel 301, the outlet of the air guide channel 301 is communicated with the water storage chamber 101, and the inlet of the air guide channel 301 is communicated with the air outlet of the fan device 20;

[0044] The stirring device 40 includes a driving motor 41 and a stirring blade 42 . The driving motor 41 is located in the installation cavity 102 , and the stirring blade 42 is located in the water storage cavity 101 . The stirring blade 42 is drivingly connected to the rotating shaft of the driving motor 41 .

[0045] The kettle body 10 can heat the water in the water storage chamber 101 to boiling. The water storage chamber 101 can be used to store water. For example, a heating element is provided on the outer wall or the inner wall of the water storage chamber 101 to heat the water in the water storage chamber 101. The installation chamber 102 can provide space for installing components such as the fan device 20, the stirring device 40, and the control circuit board.

[0046] The fan device 20 can be used to generate suction, so that the external air can enter the fan device 20 from the first through hole 103 to be accelerated, forming an airflow with a certain speed and then discharged. The fan device 20 can be, but is not limited to, a device that can generate suction and discharge airflow, such as a fan or an air pump. For example, the fan device 20 is a blower. When the blower is started, the external air is introduced into the blower through the first through hole 103 and passes through the high-speed rotating blades to accelerate the airflow, and then discharged into the air guide channel 301.

[0047] The air duct housing 30 may be, but is not limited to, a non-metallic housing or a metal housing. For example, the air duct housing 30 is a plastic housing, and an air guide channel 301 is formed in the plastic housing and communicates with the water storage chamber 101. The air duct housing 30 may be installed inside the kettle body 12, or may be installed on the periphery of the air duct housing 30. Based on the air outlet of the fan device 20 being communicated with the inlet of the air guide channel 301, the airflow generated by the fan device 20 enters the air guide channel 301 and is discharged into the water storage chamber 101. The water in the water storage chamber 101 inputs an airflow with a lower temperature, thereby accelerating the cooling of the water in the water storage chamber 101.

[0048] The spout 121 on the kettle body 10 can be used to maintain the pressure balance in the water storage chamber 101. Specifically, the fan device 20 sucks airflow from the first through hole 103 and introduces it into the air guide channel 301. The airflow is discharged from the air guide channel 301 and then enters the water storage chamber 101. The low-temperature airflow exchanges heat with the high-temperature water and then is discharged from the spout 121, thereby achieving safe and efficient cooling.

[0049] The driving motor 41 can be used to drive the stirring blade 42 located in the water storage chamber 101 to rotate. The stirring blade 42 rotates in the water storage chamber 101 to form a vortex in the water storage chamber 101, thereby increasing the heat dissipation area, accelerating the heat conduction between the airflow and the water, and thus improving the cooling effect. In addition, when the water is about to boil, the bubbles generated will make a sound of bubbles bursting on the heating plate in the kettle body 10. By making the stirring blade 42 rotate slowly to eliminate the formation of bubbles, the bursting sound of bubbles is eliminated, thereby achieving a silent effect.

[0050] The kettle in each of the above embodiments includes a kettle body 10, a fan device 20, an air duct housing 30 and a stirring device 40. The air outlet of the fan device 20 is connected to the inlet of the air guide channel 301. The fan device 20 introduces external air into the fan device 20 through the first through hole 103, and accelerates the airflow through the high-speed rotating blades, and then introduces it into the air guide channel 301. The airflow is input into the water storage chamber 101 through the air guide channel 301, and heat is transferred between the airflow at a lower temperature and the water at a higher temperature, thereby accelerating the cooling. A stirring blade 42 is provided in the water storage chamber 101, and the driving motor 41 drives the stirring blade 42 to rotate in the water storage chamber 101, so that a vortex is formed in the water storage chamber 101, thereby increasing the heat dissipation area, accelerating the heat transfer between the airflow and the water, and thus improving the cooling effect. In addition, the stirring blade 42 rotates slowly when the water is about to boil, which can eliminate the formation of bubbles and achieve a silent effect.

[0051] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the stirring blade 42 is a rod structure, the length direction of the stirring blade 42 is parallel to the horizontal direction, and the length of the stirring blade 42 is smaller than the radius of the water storage chamber 101.

[0052] Among them, the stirring blade 42 can also be but not limited to a metal rod body or a non-metal rod body, for example, the stirring blade 42 is a stainless steel rod body. The length of the stirring blade 42 can be one-third of the diameter of the water storage chamber 101. It should be noted that in other embodiments, the length of the stirring blade 42 can also be one-quarter, one-half, etc. of the diameter of the water storage chamber 101. Based on the fact that the length of the stirring blade 42 is smaller than the radius of the water storage chamber 101, the stirring blade 42 can generate a better vortex when the water storage chamber 101 rotates, avoiding the stirring resistance caused by the stirring blade 42 being too long, which makes it difficult to generate a vortex, or the stirring blade 42 being too short, resulting in a smaller vortex area.

[0053] like Figure 2 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the center line of the stirring blade 42 coincides with the center line of the water storage chamber 101 .

[0054] The center line of the stirring blade 42 coincides with the center line of the water storage chamber 101 , so that when the stirring blade 42 rotates in the water storage chamber 101 , a vortex with the center line of the water storage chamber 101 as the axis is generated to increase the heat dissipation area and improve the heat dissipation efficiency.

[0055] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the outlet of the air guide channel 301 is distributed on the top of the kettle body 10.

[0056] The outlet of the air guide channel 301 is located at the top of the kettle body 10, so that the airflow discharged from the air guide channel 301 is directly blown to the water surface in the water storage chamber 101. In addition, by setting the outlet of the air guide channel 301 at the top of the kettle body 10, the water storage capacity of the water storage chamber 101 can be ensured, and the water is prevented from backflowing into the air guide channel 301 when boiling in the water storage chamber 101. It should be noted that in other embodiments, the outlet of the air guide channel 301 can also be distributed on the outer wall of the kettle body 10.

[0057] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the outlet direction of the air guide channel 301 intersects with the center line of the water storage chamber 101 to form an angle a, and the angle a satisfies the relationship: 25°≤a≤30°.

[0058] Among them, when the airflow is discharged from the air guide channel 301 to the water storage chamber 101, an angle a is formed between the wind direction of the airflow and the center line of the water storage chamber 101, and the angle satisfies the relationship of 25°≤a≤30°, so that the airflow discharged from the air guide channel 301 blows to the middle of the water storage chamber 101, thereby maximizing the contact area between the airflow and the water surface and improving the heat dissipation efficiency.

[0059] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: a one-way valve 50 is installed in the air guide channel 301 , and the air guide channel 301 is selectively connected to the water storage chamber 101 through the one-way valve 50 .

[0060] Among them, a one-way valve 50 is arranged in the air guide channel 301, and the one-way valve 50 can control the air guide channel 301 to be connected or cut off with the water storage chamber 101. Exemplarily, when the water in the water storage chamber 101 is heated, the one-way valve 50 is closed, and the air guide channel 301 is connected and cut off with the water storage chamber 101, so as to prevent the steam of the water during the heating process from entering the installation chamber 102 through the air guide channel 301, and affecting the fan device 20, the control circuit board, etc. in the installation chamber 102. When the water is heated, the water needs to be cooled down quickly. At this time, the one-way valve 50 is opened, the air guide channel 301 is connected with the water storage chamber 101, and the cold air generated by the fan device 20 enters the water storage chamber 101 through the air guide channel 301.

[0061] like Figure 2 and Figure 3As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: the one-way valve 50 is a baffle, which can rotate relative to the air duct housing 30 and form at least a first position and a second position. When the fan device 20 stops working, the baffle is in the first position, and the connection between the air guide channel 301 and the water storage chamber 101 is cut off; when the fan device 20 is working, the baffle is in the second position, and the air guide channel 301 is connected to the water storage chamber 101.

[0062] The one-way valve 50 is a baffle structure, and the baffle can rotate relative to the air duct housing 30. For example, when the fan device 20 is working, the airflow generated by it pushes the baffle to rotate from the first position to the second position. At this time, the one-way valve 50 is in an open state, and the air guide channel 301 is connected to the water storage chamber 101. When the fan device 20 stops working, the baffle rotates from the second position to the first position under the action of its own gravity. At this time, the one-way valve 50 is in a closed state, and the air guide channel 301 is disconnected from the water storage chamber 101. It should be noted that the one-way valve 50 can also be a solenoid valve, which can be linked with the fan device 20. When the fan device 20 is working, the solenoid valve is triggered to open, and when the fan device 20 stops working, the solenoid valve is triggered to close.

[0063] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, the present embodiment further defines that: the air duct shell 30 is distributed on the periphery of the kettle body 10, and the two ends of the air duct shell 30 are respectively connected to the kettle body 10, and a second through hole 104 is formed between the air duct shell 30 and the kettle body 10.

[0064] Among them, the air duct shell 30 is distributed on the periphery of the kettle body 10, and a second through hole 104 is formed between the air duct shell 30 and the kettle body 10. The air duct shell 30 can be used as a handle, which neither affects the user's hand-held movement nor causes the overall volume of the kettle to increase, making the overall design of the kettle reasonable.

[0065] In addition to the features of the above embodiment, the present embodiment further defines that the air duct housing 30 is detachably connected to the kettle body 10. Since the air duct housing 30 and the kettle body 10 are detachable, the air guide channel 301 can be cleaned separately to avoid the air duct housing 30 being unable to be cleaned during long-term use.

[0066] In addition to the features of the above embodiment, this embodiment further defines that: a first air filter is provided in the air guide channel 301. Based on the first air filter provided in the air guide channel 301, the airflow entering the water storage chamber 101 is purified to avoid contamination of the water in the water storage chamber 101.

[0067] like Figures 2 to 3As shown, in addition to the features of the above embodiments, the present embodiment further defines: the kettle body 10 includes an upper cover 11, a kettle body 12, and a heating plate 13. The upper cover 11 is arranged on the kettle body 12 or the air duct housing 30. The heating plate 13 is arranged on the kettle body 12, and the heating plate 13 divides the space formed inside the kettle body 12 into a water storage chamber 101 and an installation chamber 102. The kettle body 12 is provided with a first through hole 103. The rotating shaft of the driving motor 41 passes through the heating plate 13, extends into the water storage chamber 101, and is transmission-connected to the stirring blade 42.

[0068] Among them, the upper cover 11 can be rotatably connected to the kettle body 12 or the air duct housing 30. For example, the upper cover 11 is rotatably connected to the air duct housing 30. When the water in the water storage chamber 101 needs to be cooled, the upper cover 11 can be rotated relative to the air duct housing 30 so that the opening of the water storage chamber 101 is fully in contact with the outside air, and at the same time, the air flow discharged from the air guide channel 301 is not affected and blown to the water surface of the water storage chamber 101. Based on the heating plate 13, the space inside the kettle body 12 is divided into a water storage chamber 101 and an installation chamber 102. Specifically, the water storage chamber 101 is above the heating plate 13, and the installation chamber 102 is below the heating plate 13. The rotating shaft of the driving motor 41 passes through the heating plate 13 and extends into the water storage chamber 101 to be transmission-connected with the stirring blade 42. A sealing ring is sleeved on the rotating shaft, and the sealing ring is used to seal the gap between the rotating shaft and the heating plate 13.

[0069] like Figure 4 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: the kettle body 10 also includes a power socket 14, a hollow portion 105 is provided on the power socket 14, the first through hole 103 is connected to the outside through the hollow portion 105, and the power socket 14 is electrically connected to the heating plate 13.

[0070] The power socket 14 can supply power to the heating plate 13. Specifically, a power supply module is provided on the power socket 14, a coupler electrically connected to the power supply module is provided at the bottom of the kettle body 12, the coupler is electrically connected to the heating plate 13, the power supply module, the coupler and the heating plate 13 form a power supply circuit, and a hollow portion 105 is provided on the power socket 14, and the first through hole 103 is connected to the outside through the hollow portion 105. In addition, the power socket 14 can be detachably connected to the kettle body 12, and can be quickly disassembled without affecting the air intake of the first through hole 103.

[0071] In addition to the features of the above embodiment, this embodiment further defines that: a second air filter is provided at the hollow portion 105. Based on the second air filter provided in the hollow portion 105, the airflow entering the water storage chamber 101 is purified to avoid contamination of the water in the water storage chamber 101.

[0072] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present utility model patent shall be subject to the attached claims.
